摘要
采用静电纺丝法制备了聚乙烯吡咯烷酮/钛酸正丁酯复合纳米纤维,经高温煅烧得到纯的TiO2纳米纤维材料并通过对罗丹明B的降解,研究了TiO2纳米纤维材料的光催化性能.结果表明,TiO2纳米纤维具有良好的光催化活性.
The nanofibers of polyvinylpyrrolidone/tetrabutyl titanate composites were prepared by using the electrospinning technique. Then, the pure TiO2 nanofibers were obtained by calcining at 500,600 and 700 ℃. The photocatalytic activity of the TiO2 nanofibers were studied by photocatalytic degradation of rhodamine B. The results showed that the TiO2 nanofibers provided with a good photocatalytic activity.
